程式碼樣式規則選項Code style rule options

您可以藉由在 EditorConfig檔中定義 .net 程式碼樣式規則選項,在程式碼基底中定義和維護一致的程式 代碼樣式You can define and maintain consistent code style in your codebase by defining .NET code style rule options in an EditorConfig file. 當您編輯程式碼時,這些規則會由各種開發 Ide (例如 Visual Studio)呈現。These rules are surfaced by various development IDEs, such as Visual Studio, as you edit your code. 針對 .NET 專案,也可以 在組建階段強制執行這些規則。For .NET projects, these rules can also be enforced at build time. 您可以啟用或停用個別規則,並透過嚴重性層級設定您想要強制執行每個規則的程度。You can enable or disable individual rules and configure the degree to which you want each rule enforced, via a severity level.

提示

  • 當您在 EditorConfig 檔中定義程式碼樣式選項時,您要設定程式 代碼樣式分析器 分析程式碼的方式。When you define code style options in an EditorConfig file, you're configuring how you want the code style analyzers to analyze your code. EditorConfig 檔案是這些分析器的設定檔。The EditorConfig file is the configuration file for these analyzers.

  • 您也可以在 [ 文字編輯器選項 ] 對話方塊的 Visual Studio 中設定程式碼樣式選項。Code style options can also be set in Visual Studio in the Text editor options dialog. 這些是每個使用者的選項,這些選項只會在 Visual Studio 中編輯時遵守。These are per-user options that are only respected while editing in Visual Studio. 這些選項不會在組建階段或其他 Ide 中遵守。These options are not respected at build time or by other IDEs. 此外,如果在 Visual Studio 中開啟的專案或方案具有 EditorConfig 檔案,則會優先使用 EditorConfig 檔中的選項。Additionally, if the project or solution opened inside Visual Studio has an EditorConfig file, then options from the EditorConfig file take precedence.

程式碼樣式規則分成下列子類別:Code style rules are divided into following subcategories:

這些子類別中的每一個都會定義自己的語法來指定選項。Each of these subcategories defines its own syntax for specifying options. 如需這些規則和對應選項的詳細資訊,請參閱程式 代碼樣式規則參考For more information about these rules and the corresponding options, see Code style rule reference.

EditorConfig 檔案範例Example EditorConfig file

為協助您開始使用,以下是具有預設選項的 editorconfig 檔案範例 To help you get started, here is an example .editorconfig file with the default options.

提示

在 Visual Studio 中,您可以產生此檔案,並將其儲存至 [工具 > 選項 > 文字編輯器] > [c #Basic] > 程式 代碼樣式 > 一般 的專案。In Visual Studio, you can generate this file and save it to a project at Tools > Options > Text Editor > [C# or Basic] > Code Style > General. 然後,按一下 [設定] 按鈕中的 [ 產生 editorconfig 檔案]。Then, click the Generate .editorconfig file from settings button. 如需詳細資訊,請參閱程式 代碼樣式喜好設定。For more information, see Code style preferences.
